  • an example of an electronic cutting machine may include a cutting element for cutting a sheet of material, drive rollers for controlling movement of the sheet, and electronics for controlling movement of the cutting element and the drive rollers.
  • the electronic cutting machine operates by moving the cutting element in an "x-direction" and the sheet in a "y- ⁇ !irection.” That is, when the cutting element is placed against the sheet, a controlled cut is made by moving the cutting element back and forth while the sheet is moved perpendicular to the movement of the cutting element.
  • the cutting element is moveable in a "z-direction" to allow desired placement of the cutter against the medium being cut at a specific location and to lift the cutting element when a particular cut is complete.
  • the electronic cutter as described herein may be configured to operate as a stand-alone machine without any need for connection to a personal computer or other external device. All of the functions of the electronic cutting machine can be controlled by the user through a user interface provided on the electronic cutter.
  • various shapes to be cut with the electronic cutter are provided on a separate cartridge. When a user desires a particular image, a cartridge containing that image is connected to the machine. The user can then select the image to be cut using the user interface, such as a keypad, and instruct the machine to cut the image.

  • the cartridge is removable from the electronic cutter.
  • the cartridges may contain a library of shapes that the user may select for cutting.
  • the shapes for being cut are stored in memory on the machine. The user then uses the user interface to select a particular shape or series of shapes to be cut from the library of shapes stored on the machine.
  • a bottom door forms a support tray for the paper being cut while the upper door reveals the user interface when opened.
  • the sheet to be cut is placed upon a mat having a tacky adhesive applied thereto for removably retaining the sheet.
  • the mat and sheet are inserted into the machine and the blade holder is moved using the user interface over a select position on the mat.
  • the desired shape is selected for cutting and the machine is instructed to cut the shape.
  • each image or shape may be further customized before cutting.
  • the image may be scaled by the user by selecting a desired shape of the image and rotating a sizing wheel until the desired size is displayed.
  • the cutting element is comprised of a blade holder and a blade.
  • the blade holder allows the blade to freely swivel within the blade holder so that the blade will orient itself in the direction of the cut being made.
  • the blade holder allows for the length of blade extending from the blade housing to be easily and precisely adjusted by a user.
  • the blade housing is configured to precisely set the blade within the housing during the manufacturing process to ensure that each blade holder/blade assembly is properly configured.
  • FIGS. 1A - 1D illustrate an electronic cutter, generally indicated at 10.
  • the electronic cutter 10 is a stand-alone machine that is fully functional without the need for connection to an external computer. All of the cutting components of the cutter 10 are housed within the external housing, generally indicated at 12, of the cutter 10. In addition, all of the software and electronics for driving the cutting components of the cutter 10 are housed within the external housing, as well as a removable and/or downloadable memory storage device for containing images, shapes, fonts and the like to be cut by the cutting components, so that the unit is fully operational and self contained.
  • the housing is provided with recesses 14 on its left and right sides 15 and 16 for providing a place to grasp the sides 15 and 16 of the cutter 10 for lifting and carrying.
  • rotatable wheels or dials 18, 19 and 20 protrude through the housing 12.
  • the wheels 18, 19 and 20 are rotatable by a user to alter certain parameters of the cutter 10 such as the size of the image to be cut, the pressure of the blade when cutting, and the speed of cutting.
  • the speed and pressure of the cutting process can be modified based upon the type of material being cut to prevent tearing of the material and/or to ensure that the blade is completely cutting through the material.
  • Rotation of the dials 18, 19 and 20 will change parameters visible on the user display 35.
  • the dial 20 may be employed to modify the size of the image or shape to be cut.
  • rotation of the dial 20 triggers a change in the image size shown in the display 35.
  • the sizes may include in inches 1 , VA, VA, 2, 2Y 2 , 3, VA, ⁇ , AVz, 5 and 5 1 / 2 ) .
  • dial 20 is linked to image size when cut
  • the cutter 10 will automatically adjust the size of the image or shape to be cut and subsequently cut an image of approximately the size indicated (in height) when instructed by the user to cut.
  • the dials 18 and 19 are electronically connected to the processor of the machine 10 to change and indicate in the display 35 to a user the pressure of the cut and the speed of the cut.
  • Display 35 may be used to display operating parameters, user selections, position information, general status, etc. Moreover, where space is not available on display 35 to show all information contemporaneously, scrolling text may be used to show a large amount of information. For example, where multiple characters are selected for cutting, a scrolling text display may be used to show the user the entire message that is selected for cutting. When the user desired to edit the message, the selected message may be scrolled from side-to-side using the direction keys and highlighting or underlining may be used to indicate the selected character. [0061] Display 35 may also include the functionality to show the user's adjustments in real time for features such as cutting size, cutting speed, and cutting pressure. The user may "dial in" the desired setting based on the value shown in display 35.
  • display 35 may highlight the parameter being adjusted to draw the user's attention to it. For example, when cutting size is being adjusted, display 35 may highlight cutting size and non-highlight the other parameters. In this way, the user is immediately drawn to the parameter under adjustment.
  • Other features of display 35 may include the presentation of warning and/or error message. If a warning or error is present, display 35 may switch the output to the warning/error and override the user's current operation. If desired, display 35 may also be used to present the user with questions, and keypad 40 may be used to receive the user's answer.
  • Each dial 18, 19 and 20, in an example, may be connected to a potentiometer or other device known in the art for sending a signal to the processor of the machine to change the corresponding parameter.
  • dial 20 may be connected to a rotary encoder (e.g., an optical or mechanical encoder) to provide rotational positioning information to the processor (discussed below).
  • the machine With specific reference to the speed of the cut, in addition to manual adjustment of the speed through manipulation of one of the dials, the machine itself may be configured to automatically adjust the speed depending upon the pressure set by the user, which may indicate a thicker material being cut. In addition, for a given speed of cut, as may be set by the user, the machine will adjust the speed of the cut depending upon the curvature of the cut being made.
  • dials 18, 19 and 20 may be configured using a variety of technologies.
  • dial 20 may be configured as a potentiometer, an optical rotary encoder, a mechanical rotary encoder, a variable reluctance sensor, etc.
  • a variable reluctance-type sensor may be more advantageous than a potentiometer or rotary encoder.
  • speed information may still be derived in firmware from the other sensor technologies (although not directly measured).
  • a particular sensor technology may be more desirable than another may (although each may be used).
  • the velocity-based detection methods for dials 18, 19, and 20 allow a user to quickly dial-in a precise setting. With large or rapid movement of the dial, very large changes in setting occur. However, as the user approaches the target value, the user slows the motion of the wheel, which provides for fine control. In this way, the user may rapidly modify setting without large numbers of rotations.

  • the "Mix 'n match" mode button allows each character to have a separate feature setting. When turned off, all entered characters through the keyboard 66 use the same creative feature setting. When the mode is selected, the character entered may have a separate creative feature for that character. This allows the user to enter a character and then choose a particular creative feature to be added to that character (such as one of the character features 152 shown in FIG. 4).
  • the OK button 65 is provided to allow the user to proceed since the selection resets the environment back to only one feature selected.
  • the Auto Fill mode calculates how many copies of the selected characters can fit on the remainder of the page to be cut. The auto fill will turn off "Fit to Page” or "Quantity" when pressed. The display 62 will show how many copies will fit on the sheet prior to cutting.
  • the Fit to Page mode calculates the best and maximum size of the selected glyphs (images or letters) to be cut and sizes them up or down to fit on the remainder of the page. That is, if an image has already been cut by the machine on the sheet currently loaded, the fit to sheet feature will know how much of the sheet is left for cutting and adjust the sizes of the images to be cut to fit within the remaining space. As such, as with many of the other features or modes described herein, because the machine knows how much has already been cut from a sheet and where on that sheet such cutting has occurred, it can adjust any selected modes or features to be cut in the remaining paper. Thus, unlike a typical "fit to sheet" selection as may be found in printing programs to fit to a particular sheet of paper, the cutter adjusts the fitting on the fly as the usable size of the remaining sheet decreases with each successive cut.
  • the "Fit to Length” mode changes the parameters of the size dial, previously discussed, to become a selector for overall length of cut.
  • the feature essentially becomes a Fit to Page cousin where the overall glyph(s) length is crunched down (e.g., reduced) to fit the dialed-in size selected.
  • the range of the size would necessarily be limited by the page length left for cutting.
  • the machine effectively ignores the current size setting when this feature is selected.
  • the "Portrait” mode changes the direction of the cutting from lengthwise to a left to right manner. This may require an OK button 65 confirmation since the machine would auto unload and restart the orientation of the entire cutting mat.
  • the portrait feature allows for the orientation of the mat to be customized in a portrait (see FIG. 13A) vs. landscape (see FIG. 13B) mode.
  • the quantity mode when pressed activates cursor keys to increase/decrease the quantity count.
  • the user can press the OK button 65 to set the quantity.
  • the first time the CUT button is pressed the display 62 will show "Quantity NNN will require XX pages. Press CUT to begin cutting the first page.” This informs the user that the quantity selected may require more than one sheet for cutting with NNN and XX representing numbers. After each page is cut, the display will show "YY more pages to cut. Load another page too continue cutting or press STOP to exit.” Thus, after each page, the user can decide to continue by inserting another sheet and pressing the CUT button or cease the cutting of the selected quantity by pressing the STOP button.
  • Quantity and Fit to Page or Fit to Length could be used together.
  • the Quantity filed appears on the display 62 when the Quantity feature has been selected by the user.
  • the Flip mode button when selected causes the selected image to be cut as a "mirror" image of the selected glyph. This feature may apply individually to all selected glyphs.

  • the user can adjust the pressure applied by the solenoid to the blade with one of the dials shown in FIG. 1.
  • Such pressure adjustment may be required to properly cut a given material. For example, a pressure setting to cut a sheet of regular paper may not be adequate to cause a proper cut into thick card stock. As such, the pressure may need to be increased. Conversely, the pressure necessary to cut through thick card stock may cause the blade to tear a regular sheet of paper if a cut is attempted at too high of a pressure setting.

  • the back surface of the machine includes an elongate opening for allowing the mat to protrude through the opening during the cutting process. Also provided is a power adapter port for connecting to an electrical power cord and a USB port for attaching the cutter to an external computer. As previously discussed, however, the cutter may be fully operated without the use of an external computer attached thereto. The connection is therefore provided to all the firmware of the machine to be updated as well as for communication with the machine to allow content stored on a particular cartridge to be updated through the machine.
  • the machine is also provided with various unique features such as "Paper Save.” This setting will automatically rearrange the selected shapes to cluster them together and take advantage of otherwise empty space on the paper.
  • the cutting machine has vast capabilities that allow the user to customize the images, characters and/or shapes to be cut.
  • each cartridge contains and associated overlay provides feature buttons for custom feature effects. These features may vary with each specific cartridge to add a powerful element of expansion and versatility.
  • the arrow buttons that surround the CUT button can be used to guide the blade to a desired location. This is very useful when needing to cut in a certain spot on the paper, especially to avoid waste. When moving away from the starting point 708 indicated on the cutting mat, the size of the image might need to be reduced in order for the machine to cut the image.
  • the machine will alert the user and allow the user to reduce the size of the image to be cut. If sizes other than the standard size of paper for the machine are used, the user can use the blade positioning buttons and size dial to adjust for the given paper size. By pressing the "Set Paper Size” button, the user can input a custom paper size into the machine and the machine will know where "home” cut position is for the loaded sheet. The machine will cut lengthwise with “down”, as defined by the bottom of the image, being toward the left edge of the paper when viewing the machine from the front. [00128] If material to be cut other than regular paper or cardstock is selected, the machine may be customized for such other materials.
  • the pressure dial may need to be rotated to increase or decrease the pressure of the blade against the material to be cut to allow the blade to completely cut through the material without tearing the material.
  • some paper materials may require a slower cutting speed.
  • the speed dial can be decreased to allow the blade to cut without tearing.
  • the blade depth can be adjusted by rotating the blade housing adjustment knob as previously discussed.
  • the rotation feature may be employed through an additional dial that allows the user to "spin" the glyph around a central axis, but also allows the glyph to be rotated at set intervals, such as 45-degree and/or 90-degree increments.
  • Digital sizing may be accomplished with, for example, rotation of dial 20 (see FIG. 1) or using keys associated with rotation on the keypad, or using the soft keys.
  • each character may be assigned different attributes.
  • Each attribute may be set by selecting the existing character (e.g., using positioning keys and the display) and using the keyboard 40 or dials 18, 19, 20 to modify the features. For example, size, position, rotation, skew, italic, and other parameters may be modified for each character or shape.
  • each graphic or shape may be individually customized for the features. Alternatively, the user may apply the customized features to all of the characters/shapes.
  • Each character maintains its own list of "feature" attributes based on the user's selection or customization.
  • the user may move a cursor on the display to select a character. The user may then review and/or modify any feature selection for the selected character.
  • various feature button LEDs may become lighted when a feature is selected. In this way, the feature selection buttons provide feedback to the user as to the status of the feature as applied to the selected character.
  • Such a system providing for the assignment of features to each individual character may be called a mix-and-match system (e.g., or a "mix-'n-match” feature).
  • Other system features may include a "flip" feature that allows for mirroring of a character/shape (see FIG. 17).
  • the user's selection of the "flip” feature allows the user to mirror a character along a vertical center-line of the character.
  • This feature is useful, in an example, as allowing the user of paper when cut from the "back" side (e.g., when using a self-adhesive).
  • An "auto-fill” feature may be used to fill a page with as many instances of the current character/shape as will generally fit on the remainder of the page. The auto-fill feature can be useful when cutting a large number of the same shape.
  • An "auto-expand" feature allows for the resizing of a character/shape or a collection of characters/shapes to generally fill the remainder of the page.
  • the auto- expand feature may be used to maximize the used are of the page.
  • the auto-expand function is applied to a collection of twelve characters/shapes. The entire collection is scaled up to cover the entire page. Thus, maximizing the size of the collection given the page size.
  • a "quantity” feature allows the user to select the number of cuts that are applied to the current characters selected, or the collection. For example, when the quantity feature is selected, the user is queried for the "number of cuts" (e.g., the number of total number of times each character will be cut). The user may press the "quantity” button (e.g., on the keyboard) and then enter the number of cuts using dial 20 or the arrow keys on the keyboard. The user is then prompted to begin cutting. Once cutting is authorized by the user, the display may show the status of the number of cuts, providing an indication of cutting progress to the user. If multiple pages are required to complete the number of cuts, the system prompts the user to insert a new page and then resume the cutting operation.
  • the number of cuts e.g., the number of total number of times each character will be cut.
  • the user may press the "quantity” button (e.g., on the keyboard) and then enter the number of cuts using dial 20 or the arrow keys on the keyboard. The user is then prompted to begin
  • a "center point” feature allows the user to cut a shape around a center point.
  • the user sets up the center point function by positioning the cutter over the center of the desired cut area.
  • the user then presses the "center point” button on the keyboard to indicate the center position.
  • the user selects the shape to be cut and then initiates the cutting operation.
  • One example of the center point feature includes cutting an oval shape from a photograph (shown in FIG. 18).
  • a "multi-cut" feature may be useful to make multiple cuts along the same lines. This allows for cutting of thicker material, such as chipboard.
  • a first pass is made to initially cut the material, but may not cut all the way through the material.
  • a second pass e.g., of the multiple cutting function
  • another cut is made following the path of the original cut. This allows the blade to cut deeper into the material.
  • the number of re-cuts the machine makes may be set either by a setup feature or in response to user prompt each time the feature is turned on.
  • a "line return” feature would allow the user to insert line returns such as is allowed when using a word processor (see FIG. 19). This gives the user greater flexibility for configuring the cutting pattern, for example when the user wishes to leave a larger rectangular area in one corner of the mat for placing a larger character/symbol.
  • shape refers to a particular image, font or character that may be stored on the machine of the present invention, on a cartridge for the machine or in any other location for being cut by the machine.
  • sheet refers to any material in sheet form that can be cut with electronic cutter 10 as described herein, including without limitation papers of various thicknesses including such materials as colored papers and card stock as well as sheets of plastic, cardboard, foil or other materials known in the art. It is also understood that, as used herein and in the appended claims, the singular forms “a,” “an,” and “the” include plural reference, unless the context clearly dictates otherwise.
